The below is likely overkill and a good bit of work to setup, but it is
also very flexible. Maybe it suits your needs.

The Markdown-to-XML conversion can be tuned to include all the relevant
information. E.g., you could use pandoc with a custom writer to produce
the XML format of your choice. The link below is an example XML writer
that can be tuned as needed.


With that setup, one can modify the `Image` function to produce the
output you need. E.g., match on the file name extension use the library
function `pandoc.path.split_extension` and then change the element type
depending on the extension.

This way you'd have all the important information in your XML.
More info:  and
.

Of course, you could also use pandoc to go directly to ConTeXt; that is
currently my preferred way of producing PDF from Markdown.

Cheers,
Albert

Thanks for reporting! We must have missed this one while testing. It
should be fixed.

If you for the moment can live without splitting, then this seems to
give you the formula number where expected:

\placeformula
\startformula[location=left,split=no,numberlocation=overlay]
a^2 + b^2 = c^2.
\stopformula

(or put the keys in \setupformula)

I hope it helps.

[NTG-context] french quotation marks

2022-07-12 Thread Henning Hraban Ramm via ntg-context 
Hi, according to my knowledge (and also Wikipedia), French uses « … » as 
double (\quotation) and ‹ … › as single (\quote) quotation marks.


The current setting in ConTeXt however is « … » for both, just with less 
spacing for \quote.

If no francophone user objects I’d suggest to fix this.

[NTG-context] fullhz, kerning and glue

2022-07-12 Thread Henning Hraban Ramm via ntg-context 

Hi,
I just added an explanation of "fullhz" to the options in 
https://wiki.contextgarden.net/Command/setupalign.

but I’m actually unsure if it’s right.

In the sources I found:
https://source.contextgarden.net/tex/context/base/mkxl/hand-ini.mkxl

%D At some point we can introduce extreme expansion, i.e. \type 
{\normaladjustspacing\plustwo}.

56
57% 0 = disabled
58% 1 = notused  (thesis)
59% 2 = glyph + kern
60% 3 = glyph only   (default)
61
62\def\font_expansion_enable  {\normaladjustspacing\plusthree}
63\def\font_expansion_enable_k{\normaladjustspacing\plustwo}
64%def\font_expansion_enable_n{\normaladjustspacing\plusone}
65\def\font_expansion_disable {\normaladjustspacing\zerocount}

And "fullhz" in spac-ali.mkxl calls \font_expansion_enable_k.

So, apparently fullhz enables stretching of *kerning* – that sounds to 
me like letterspacing.


OTOH in my notes (and thus in my book) I have the information that 
fullhz enables stretching of *glue*, and I thought that would mean 
whitespace outside of words.


Please enlighten me?

Assuming that Pandoc markdown is being used, you should be able to set 
class attributes on each image. You can then associate external figure 
definitions with specific classes, and process each individually. 
(Pandoc user guide, link_attributes 
)

When you use XML as input you can add additional code to the setups block
which uses \externalfigure to load the image.


\setupexternalfigures [location={local,global,default}]

\defineexternalfigure [jpg] [width=4cm]
\defineexternalfigure [png] [width=8cm]

\starttexdefinition includegraphics #1

    \splitfilename{#1}

    \processaction
    [\splitofftype]
    [    jpg=>{\externalfigure[#1][jpg]},
 png=>{\externalfigure[#1][png]},

[NTG-context] Bug in placeformula

2022-07-12 Thread Otared Kavian via ntg-context 
Dear Hans, dear Mikael,

In my experiments with the new math engine, I noticed that there is an issue 
with \placeformula when one sets the location of the numbers on the left: the 
number is one line above the formula. Here is a minimal example:

% begin bug-placeformula-left.tex
\setupformulas[location=left]

\starttext

\placeformula
\startformula
a^2 + b^2 = c^2.
\stopformula

\stoptext
% end bug-placeformula-left.tex

Moreover, in some environments (such as enumerations) the bug destroys 
completely the flow of text but I could not set up a minimal example to send 
you.

Best regards: Otared

[NTG-context] LMTX and modules

2022-07-12 Thread Axel Kielhorn via ntg-context 
Hello,

Some years ago I wrote an introduction to ConTeXt in German:

https://github.com/AKielhorn/Context-Intro

But that was long ago.

Today LMTX is state of the art and I tried to build it with a recent LMTX.

This lead to problems because LMTX does not include modules.

Therefore my question is:
Is the a plan to include modules into the regular LMTX installation?

If not, is there a way to test for a certain module?

\doiffileexists{m-module}
\usemodule{module}

Greetings
Axel
